Formula: C12H9N3. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 2-(Pyridin-4-yl)-1H-benzo[d]imidazole, is researched, Molecular C12H9N3, CAS is 2208-59-5, about Synthesis and crystal structure of a novel tetranuclear zinc(II) coordination polymer [Zn4(o-bda)4(p-pbim)4]n.

A novel tetranuclear zinc(II) coordination polymer [Zn4(o-bda)4(p-pbim)4]n 1 (p-pbim = 4-pyridylbenzimidazole, o-bda2- = o-phenylenediacetic acid dianion) was synthesized by a hydrothermal method and characterized by elemental anal., IR and x-ray single-crystal diffraction. The title complex crystallizes in monoclinic, space group of P21/n with a 14.231(1), b 16.257(1), c 16.794(1) Å, β 100.26(1)°, Z = 8, dc = 1.573 g/cm3, μ = 1.321 mm-1, F(000) = 1856, R = 0.0420 and Rw = 0.111. The Zn(1) atom assumes a distorted trigonal bipyramidal geometry, involving three carboxyl O atoms from two different o-bda ligands and two N atoms from two p-pbim ligands. The Zn(2) atom is coordinated by two oxygens from two distinct bda2- anions and two nitrogen atoms from two p-pbim ligands to form a distorted tetrahedral geometry. The Zn(II) atoms are alternately interlinked by o-bda ligands in bis-monodentate or chelating-bidentate and monodentate modes into one-dimensional undulate chains along axis c with the adjacent Zn…Zn distances of 8.32 and 8.47 Å. Such neighboring chains are further extended into a 1D bi-chain structure with two different subrings A and B, which are 32- and 14-membered rings through interchain p-pbim ligands. There exists a 2D supramol. network linked by intermol. hydrogen-bonding interactions between the uncoordinated carboxylate O(4) atom or coordinated carboxylate O(7) atom and the uncoordinated imidazolyl N(2) and N(5) atoms with the O…N distances to be 2.695 and 2.807 Å.
This literature about this compound(2208-59-5)Formula: C12H9N3has given us a lot of inspiration, and I hope that the research on this compound(2-(Pyridin-4-yl)-1H-benzo[d]imidazole) can be further advanced. Maybe we can get more compounds in a similar way.
